Do I need to get a lawyer to sue my lawyer for taking so long with my Avandia case since I have been waiting since 2007 and been approved since 2009 and even the govt got paid b4 me?

If you wish to sue your present lawyer for malpractice, you will probably want a lawyer to litigate that for you.

The fact that your case was delayed or even lost is not proof of malpractice. You would need to fire your present attorney and hire an attorney to review the details of your file to determine whether you have a malpractice case.
